Foam kits fit perfectly, simple to install, thanks to detailed installation video. Speakers sound great and should last for another twenty-five years. Great solution.

All went well. I found the glue strange to use but it performed exactly as the directions indicated. My IMF Super COmpacts live again. Long live delightful sounding speakers. The repair cost about 2% of a current equivalent speaker and I fixed them myself. Thanks to Simply Speakers.

Was able to install foam rings onto my speakers successfully. used a little too much glue on first speaker but was able to get it attached successfully. Speakers have been working fine outdoors for a few weeks.
